DLR: Melt One-Ton Bag Bitumen at 8–10 t/h With Your Existing Boiler
Which Feiteng Bag Bitumen Melter Fits Your Site?
1단계 — 가방 들어올리기
Lift one-ton bags with the built-in hoist
The 3 kW electric hoist (2-ton capacity) with its 0.4 kW walking motor lifts each bag and travels it to the top feeding port — no crane or forklift tied up at the melter. One operator handles the whole lifting cycle from the pendant control.
2단계 — 공급
Drop bitumen blocks through the feeding ports
Operators cut the bag bottom and the bitumen block drops through the feeding port onto the buffer device, which absorbs the impact and guides the block into the tank. The buffer is what makes feeding safe and repeatable — no splashing, no shock loads on the tank structure.
Step 3 — Thermal Oil Melting
Melt with external thermal oil above 200 °C
Seamless-steel thermal oil coils (57 × 3.5 mm) transfer heat from your boiler through the tank, while 100 mm rock wool insulation and the corrugated steel outer wall keep that heat inside. Indirect oil heating melts the blocks evenly without scorching the binder at the coil surface.
Step 4 — Filtering and Pumping
Filter and pump to your storage tank
Once bitumen passes 110 °C pumping temperature, the 3QGB 80×2-46 three-screw pump moves 24 m³/h on 7.5 kW through the in-line filter, which traps bag debris and impurities. Clean liquid bitumen arrives at your storage tank or plant — and your downstream valves stay clear.
